To all whom it may concern: Be it known that I, REINHOLD H. WAP- rLEn, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in (igstoscopes, of which `the following is a speci cation.

lHeretofore, cystoscopes or instruments employed in the`r diagnosis and treatment of l amA aware, to pass the cy'stoscope into and through the urethra in an inverted position and to then turn the same around in order to have it in the position for use, and this in and of itself, is a very painful procedure; morebver, there has been a certain element of danger in the use of these instruments as hereinbefore constructed, because of the liability of thev Vparts thereof injuring the walls of the yorgan into which the instrument has been inf serted. x

New the object of my present invention is to obviate the hereinbefore named difiiculties, and in carrying outJ the same, I employ a sheath, a telescopic tube, means for conducting and guiding a catheter, and a rev'olubly operated means for directing the paths of the ends of the vcatheters,-as will be hereinafter.

- showing the guide barl turned to the posi- -tion in-which the end of the catheter is directed from a straight line ath, and Fig. 7 is a cross section on line z, 2, ig. 1, showing the- 'guidebar turned out of its right line position.

'-Refen'in to the drawing, a represents a gral therewith and set 'atan angle to the body which is provided with an eye-piece 14,` adscrew 11, which is turned down thereon and portion of the sheath a. The end portion b 1s preferably provided with cut-away parts 12 on the opposite sides thereof and with a removable ca b ada ted to contain an electric li ht bul 13 to e receivedl within the end o the off-set end portion b. The'end of the sheath a, adjacent to the 'offset portion b and in line with the under cut-awa pa'rt 12 of the end b, is alsoprovided wit -acutaway part a and on the'other end' of the sheath a is a head 10 provided with' a clamp or set screw 11. v

c represents a telescopic tube, one end bf jacent to which isa stop 15, secured on whichis a clamp member 16.4V At one end of the telesco ic tube is a liens 17'and at 'the other end a ens 18and as will be understood, intermediate lenses may be emplo edlif so desired. The telescopic tube cis a apted to be passed into thesheath'member a, and the stop 15 to abut against the head 10, `the clamp member 16 passing under the set by which means the telescopic tube member ma be maintained in the proper position Wit 'n the sheath c.

0n one side of the telesco ic-tube andrunning parallel therewith an parallel to each other, I prefer to employ?y a pair of'tubes d," e,

the inner ends of which terminate at a' oint appreciably distant from the place w erein the, lens 17is set,these 'tubes' passing through the said head /10/and-having their opposite ends passed laround the telescopic tube'c and terminating on the o posite slde thereof. These tubes d, e, are a apted toreceive and guide the vcatheters d, e', which are passed into the tubes from the outer-ends thereof. A i

Between the tubes d;eandon the under side thereof, I employ a rod f,journ'aledfin suitable bearin s 19 secured tothe-said tubes d,/,. One en of this rod f adjacent to the inner ends of the tubes d, e, is flattened as at f and carries a guide bar gwhich is pivotally `connected thereto by means fthe-pin'f20 or d, e, willassume a' p/ositifgilvith their-'ende sgg.

with a head member 21, secure towhich is a handle 22, and the head member 21 is prefer? ably journaled in a bearing 23 secured to the telescopic tube c between vthe stop 15 and the eye-piece 14. y Y

Now in the use of the hereinbefore described instrument, the sheath member a, is assed intoand through the urethra to the bladder of the patient and as hereinbcfore stated, the instrument is inserted in the position in which it is necessary to use the same; thereupon the telesco ic tube c is passed to place within the sheat a, the catheters having previouslyr been placed into the tubes d, e, to approximately the positions shown in Figs. 4 and 5; thereupon the handle 22 may be turned to turn the ro'd f and thereby cause vthe'guide bar g to move and determine the `direction of the path of the end of either catheter d', e,"the side to which the handle .v 22 is turned, depending upon which catheter is to be directed. By this it will be'apparent that the cathetersmay be directed to and passed into the ureter canals and ifuecessary passed ri ht u to the pelvesof the kidneys. f g p As 'hereinbeforestated, the longitudinal groovesl or recesses in the opposite sides of the guide bar gare made to conform to the curvatureof the catheters d', e and furthermore it is to'be noted that the longitudinal edges of the guide bar g, both above and below the grooves therein, are rounded. No`w in turning the rod f, the flattened end of the same wil be turned in thel same direction, likewise turning the guide bar g. The guide bar g may thus be turned in the arc of a circle, and being pivotally connected to the end of the rod f at 20, may also turn about'this point. lt will now be apparent that if the rod f be turned from its normal position after the catheters have vbeen placed as shown in Fi s. 4 and 5, assuming the direction of rotatlon to be clockwise, the lguide bar g will be turned with the rod f and contacting with the'catheter e will also swing on its plvotal point 20 to a position shown in Fig. 6 or that 1n Fig. 7, which latter is extreme, thereby correspondingly delecting the end of the said catheter, the amount of the deiiection dependin of course upon the angle throu h which t e rod f is turned, and because of t e rounded longitudinal edges of the Iguide bar gg, the same will automatically return to its normal position, by one edge contacting with and slidlng over the surface of the telescopic tube, when the rod f is returned to its initial osition. The other catheter d may be deected and directed by turning the rod f counter clockwise.

It will be seen that from the construction of the herein described instrument, the ends of the catheters having been passed through the ureter canals into the kidneys, may e left there in position by withdrawing the in strument, so that the diagnosis may be certain in determininor whether one or both as heretofore described, may be utilized to treat the diseased organ by forcing suitable specifics therethrough to the said organ.
